Oh god, you're serious, aren't you?
Anonymous cannot be disbanded. Anonymous cannot be destroyed. It is an amalgam of every halfway decent hacker who believes in free speech and the first amendment. There are no entrance fees, no members list, anyone who wishes to be a part of Anonymous may be a member of Anonymous, in however large or small a way they desire. Disband Anonymous? The idea is preposterous, and impossible. Even if it is possible, it certainly won't be achieved by making a post on an internet forum.
What's the reason for this? They've "Lost their way?" That we "Can't take anything they say at face value?" Are these problems supposed to be unique to Anonymous? Are you trying to say that any organization or group to which these phrases apply should destroyed and rebuilt from the ground up? By this reasoning, one could make the same claim about anything. Politicians. The media. Religion. The internet. Movies. Video games. The human race. You can't make a vague claim of "They don't have the RIGHT to be a group" without better reasoning than "They don't stand for what they originally stood for!" Especially since, far more than most organizations, they do still stand for what they originally stand for.
While I'm sure you have good intentions with this post, I'm almost entirely certain that it's in vain. The few members of Anonymous, if any, who read this post will most likely ignore it, leave you a troll face with a "U Mad, bro?", or send you a message with your IP address and some other information about you with a "WE ARE ANONYMOUS, FEAR US" at the bottom. As you said, you're trying to light a match, but I'm afraid it's already been dipped in a bucket of water.
